Patent DE-3126877-A1 (DE)
Title: Printer
Inventor: HENMI KOJIRO
IPC: G03B27/32
Filed: 1981-07-08
Abstract: The printer for use in a photomechanical process has an essentially box-like construction and uses a slot-exposing system. A photosensitive material is transported along the ceiling surface, the side wall and the floor surface of the box-shaped machine body in that sequence in such a way that during this transport said material is successively exposed, developed and dried. A slot-exposing scanner executes horizontal to and fro movements in a space between an exposure zone below the ceiling surface, where the photosensitive material is exposed during its transport horizontally along the ceiling surface, and a carrier for the original image, which carrier is arranged directly below the exposure zone and opposite thereto. A developing container, a drying device and a removal tray for taking out the photosensitive material after development and drying are arranged on the floor surface of the machine body.
Patent DE-3127659-A1 (DE)
Title: Moisture insulation for flat roofs
Inventor: ZABOROWSKI HORST
IPC: E04D13/16
Filed: 1981-07-13
Abstract: The invention relates to a moisture insulation for flat roofs, comprising individual heat-insulating panels (1) and self-adhesive connecting strips (2) which have a stable volume and are fitted together to form an imbricated skin (3) which is impermeable to water in the fluid state. In contrast to the known seals in the case of which sheets consisting of roofing felt or foils are bonded or welded together or, in the case of water-repellent-concrete roofs, are concreted in one casting operation (all said seals producing a cohesive uppermost surface which, in the case of temperature fluctuations, undergo movements from the centre and thus, on the roof edges, produce much larger stresses within the uppermost surface than in the centre of the same), the invention constitutes individual, uppermost surfaces in the case of flat roofs which have their movement centre in the respective individual heat-insulating panel (1). As a result, the movement caused by temperature fluctuations on the roof edges is equal to that in the roof centre. The individual heat-insulating panels (1) are not overlapping (as is necessary in the case of sheet-metal coverings), but are laid in an abutting manner. The connecting rods (2) seal the individual heat-insulating panels (1) with respect to one another and absorb the movements caused by temperature fluctuations. <IMAGE>
Patent DE-3130177-A1 (DE)
Title: Digital frequency mixer
Inventor: BURGER ERICH ING GRAD
IPC: H03K5/26
Filed: 1981-07-30
Abstract: The present invention relates to a mixer (M) in digital technology, having two inputs for two digital signals of different frequency (f1 and f2, respectively) and an output for the mixed signal (A). It is proposed to implement the mix as a bistable flip flop (KS) in the form of a D-type flip flop in which the signal with one frequency (f1) is present at one signal input (preparatory input V) and samples the signal with the other frequency (f2) at the data input (D) with the positive or negative edge depending on definition. At the mixer output, the value sampled in each case (A) is present until a new sample is present. The frequency ratio between the higher and lower frequency (f1/f2) is only slightly greater than one in this case. Such a mixer is used, for example, in a data multiplexor in connection with the phase synchronisation of the data clock. <IMAGE>
Patent DE-3133813-A1 (DE)
Title: Pedal-crank drive for two- and multi-wheeled vehicles
Inventor: LORENZ PAUL
IPC: B62M1/36
Filed: 1981-08-25
Abstract: The invention relates to a pedal-crank drive for two- and multi-wheeled vehicles, in particular bicycles, the crank arms of which are connected to the commercially available chain drive in such a manner that the effective length of a crank is considerably larger during the downwards pedalling than during the upwards movement. This is intended to exploit the fact that the rider can exert a stronger force on the pedal crank during its downwards movement than during the upwards movement of the same for an increase in the torque which can be generated during the downwards movement. By means of the invention, the pedal-crank drive is intended to be of such a design that only the front crank semicircle with extended lever arm be available for exerting the torque whereas the rear crank semicircle is completely free of torque and passed through quickly. This object is achieved by virtue of the fact that the pedal crankshaft (6) is divided and the two coaxial pedal crankshafts (6) which, in the direction of travel, lie before the shaft (13) of the large sprocket wheel (10), are mounted in a carrier (1) attached to the front oblique tube (3) of the frame, at least one pedal crankshaft (6) being connected via a crank (7) having a sliding piece (8), which engages in a profile rail (9) attached diametrically to the sprocket wheel (10), to the conventional chain drive. <IMAGE>
Patent DE-3134815-A1 (DE)
Title: Area protection
Inventor: HAAG GUENTER DR
IPC: F16P3/14
Filed: 1981-09-03
Abstract: Area protection in which the radiation emanating from a source covers the area to be protected. The protection is constructed in such a manner that when the radiation is influenced in the region of the area, an alarm is triggered. Along one side of the area to be protected, a source is arranged which emits radiation over its entire length; along the other side of the area, a reflecting strip (2) is arranged. On both sides of the radiation source, a radiation detector is in each case provided. The radiation emanating from each point of the radiation source reaches the receivers in each case after being reflected from the strip. The signal generated by the receivers is supplied to an evaluating circuit which triggers an alarm when the detector signal deviates from the rest state. The response threshold of the evaluating circuit can be adjusted. The novel area protection is preferably used for machine protection or for protecting against penetration or passage.

Title: Drive control device in a camera
Inventor: IWASHITA TOMONORI
IPC: G03B9/07
Filed: 1981-11-20
Abstract: A mechanism in a camera is described, the further movement of which mechanism is stopped in a set or adjusted position by means of a locking member. The operation or actuation of the locking member is controlled by driving a control member provided therefor by an electromagnetic drive source. When the abovementioned mechanism is not active, the locking member is held stationary by a retaining member. At the same time as the actuation or operation of the abovementioned mechanism is induced by an actuation member, the movement of the actuation member is further used to disengage the abovementioned retaining member from the locking member. After the drive movement of the control member has been carried out, the operation of the mechanism is then ended by the locking member.

Patent DE-3151719-A1 (DE)
Title: Auxiliary device for field cultivation
Inventor: WIEGELE FRANZ
IPC: A01D45/00
Filed: 1981-12-29
Abstract: An auxiliary device has an undercarriage and a berth mounted on it and intended for a worker lying face down on it. On the one hand, for retaining the head and therefore for relieving the neck muscles of strain, there is a retaining device which preferably has a strap engaging round the forehead region and a strap engaging round the chin region. On the other hand, the head retention at the same time also forms an abutment for support during the actuation of the drive, which can particularly be actuated by the foot. Support by the hand during the operation of the appliance is therefore unnecessary, even during braking, and consequently, even then, the picking work carried out with both hands does not have to be interrupted.
Patent DE-3200571-A1 (DE)
Title: Slotted squeegee inside a screen cylinder or the like
Inventor: MITTER MATHIAS
IPC: B41F15/44
Filed: 1982-01-12
Abstract: A slotted squeegee is designed at the lower end in such a way that it rests against the screen cylinder with a piece adapted thereto which is described as a sealing part, the sealing and application area covering a region of about 180 mm and more. It is thus achieved that, when the screen cylinder or the stencil is running, the surface pressure and the surface loading by the slotted squeegee on the screen cylinder or the stencil are low, the screen cylinder is treated gently and the comparatively wide gap, extending over the entire operating width, serves as a sealing region and prevents the application medium passing onto and smearing the inside shell surface of the stencil. <IMAGE>

Patent DE-3212989-A1 (DE)
Title: Rearview mirror
Inventor: FREUDENSCHUSS OTTO DIPL ING
IPC: B60R1/08
Filed: 1982-04-07
Abstract: An electronically controlled, electromechanically actuated control device is provided as an anti-dazzle protection on an interior rearview mirror for motor vehicles, with which control device a metal-coated glass pane is adjusted, said pane being arranged behind a weakly reflecting pane. The control circuit contains an optical measurement circuit with at least two photoelectric transducers. In order to achieve the anti-dazzle effect at the correct time even when the troublesome light source is still relatively distant and the light points in the mirror are therefore rather small, two photoelectric transducers are arranged in the optical measurement circuit in such a way that they receive the light from the dazzling light source essentially from the same direction; the two transducers are located in a contrast optical measurement circuit in different focusing planes with respect to a lens system arranged in front. As a result, a dot light measurement and an integral measurement with respect to the same light source is made possible and the two measured values are evaluated by means of contrast measurement. Therefore, the system reacts to dazzling light which originates from a vehicle following at a relatively large distance of, for example, up to 150 m.
